Abstract
The invention relates to the field of engineering equipment, in particular to a reciprocating pump cylinder sleeve compression device which comprises a bolt, a discharging liquid cylinder, a cylinder sleeve flange, a nut, a double-end stud, a cylinder sleeve gland and a gland locking disc. The reciprocating pump cylinder sleeve compression device is characterized in that the double-end stud comprises two external threaded sections; the cylinder sleeve gland comprises two arc-shaped parts and two plane parts; the gland locking disc comprises two arc-shaped parts and two plane parts; a cylinder sleeve is positioned through the cylinder sleeve flange; when the cylinder sleeve gland, the double-end stud and the nut are compressed on the discharging liquid cylinder, the torque of the nut can be controlled for compression of the cylinder sleeve; and after the cylinder sleeve is compressed, the bolt is adopted for being connected with the gland locking disc. The reciprocating pump cylinder sleeve compression device has the advantages that the plane parts of the cylinder sleeve gland are adjacent to those of the gland locking disc, so that the cylinder spacing is reduced; the nut comprises two internal threaded sections and an outer hexagonal part, thereby being beneficial to the connection torque control; and accordingly, the size of a reciprocating pump can be reduced, the working stability can be improved, the weight can be reduced, the service life can be prolonged, and the purpose of reducing the cost and improving the efficiency can be fulfilled.
Description
Technical field
The present invention relates to engineering equipment field is and in particular to a kind of reciprocal pump liner hold down gag.
Background technology
In petroleum gas field, reciprocating pump is used to convey liquid to carry out oil and gas development, such as conveys drilling fluid
To at drill bit, assist catalase, cool down drill bit, cutting carring goes out well；Or it is used for conveying fracturing fluid to carry out pressure break work
Move, or conveying liquid carries out well-flushing etc..There is no reciprocating pump, oil and gas development activity just cannot be carried out.
Due to adopting 3 cylinders or 5 cylinders reciprocating pump, the centre-to-centre spacing between cylinder sleeve flange and cylinder sleeve gland determines reciprocating pump row more
Go out the centre-to-centre spacing of fluid cylinder, and determine the length of reciprocating pump crankshaft.Generally, cylinder sleeve flange and cylinder sleeve gland are all circular, lead to
Fluid cylinder centre-to-centre spacing is larger, and crankshaft length is longer, thus leading to the volume of reciprocating pump greatly, weight weight, and high cost, transport and safeguard not
Just.
Simultaneously as cylinder sleeve gland is the structure with percussion disk, strike during tight cylinder sleeve cannot precise control moment of torsion, Wear resistance disk and
Liner packing easily lost efficacy.
Therefore, reciprocating pump volume is big, weight weight, high cost, and transport and maintenance are inconvenient, job insecurity, inefficiency.
Content of the invention
In view of this it is necessary to provide a kind of one kind quickly and easily reciprocal pump liner hold down gag.
